DESCRIPTION¶
This function get the diagonal part of a matrix.
csr<Float> a;
dia<Float> d = diag(a);
TODO¶
Build a csr matrix from a diagonal one or from a vector:
dia<Float> d;
csr<Float> a = diag(d);
vec<Float> u;
csr<Float> b = diag(u);
IMPLEMENTATION¶
template<class T, class M>
dia<T,M> diag (const csr<T,M>& a)
